How much HP on stock FRS w/ OFT? With and w/o E85? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

chazmuska · 07-03-2017, 01:23 AM

Hey guys, I'm new here. Just wanted to know if someone had a dyno graph of the stock HP vs the HP w/ OTS tune from the OFT (open flash tablet) with and without E85. I tried searching and couldn't find any. The only ones I found are the ones with custom tunes.

I just want to see the overlay from what the OFT gives in HP and torque compared to stock. I just ordered my OFT yesterday!

Don't have any dynos but from what I can remember when I first did FBO + OFT +E85 the torque curve ( which is what I personally think mattered the most) felt way more accessible during daily driving than stock. Plus a hard bump up top too. I have long since moved on from OFT BUT you won't regret it. I never did.

Power feels more linear but it's a subtle difference. OFT with Crawford BPB was a noticeable difference. No dyno graphs other than seat of the pants here. Buuut I think there are some floating around.

There are a lot of graphs here, the last of which (in the OP) should answer some of your questions.

I just went from 91 on OFT tune to Stage 2 E85 on stock header and I LOLd hard inside my car when I first felt the difference it makes, even on a stock car.

Comparing dynos between different cars on different machines will tell you very little. Dyno readings are not universal and even an unaltered car can have a large change only a day after the last pull was recorded.
You could take the same car to 10 different places on the same day and have 10 different readings. All they are really good for is benchmarking your own car or actually making adjustments while tuning it.

I just mention this so that you don't go chasing a number or think there is an issue with the car if you don't have the same results as any graphs you may find.

Ha that's awesome man!...can't wait to do the same! I just picture the nice smoothness and throttle response from stage 1 but just more of it!

You bring up a good point! It would only be worth comparing then if it was done on the same car, same day, one right after the other!

OFT, OFH and E85 are all worth about 10whp each.
